Title: Cooling blade of gas turbine
Inventor: TAKEISHI KENICHIRO
IPC: F01D5/18
Filed: 1995-06-19
Abstract: PURPOSE: To stabilize blade cooling by disposing cooling water supply tube on a middle side within a blade and disposing evaporation tube close to the surface within the blade and communicating the supply tube and the evaporation tube to each other on the blade tip side and thus forming a flow path of cooling water turning back at the blade tip and passing through the evaporation tube and going toward the blade root. CONSTITUTION: Cooling water W supplied from blade root flows through cooling water supply tubes 12, 13 from blade root to blade tip and then flows into numerous evaporation tubes 14 at position of blade tip. Cooling water entered into evaporation tubes 14 removes heat from a moving blade heater with high temperature gas flowing over surface of the moving blade. Water is thus evaporated and flows through the evaporation tube 14, and so discharged from blade root. That is, evaporation of cooling water within the evaporation tube 14 cools down the moving blade due to is latent heat, and so, temperature of the moving blade is maintained at lower than permissible temperature. Flow of fluid within the evaporation tube 14 is opposite to direction of centrifugal force F.  Thus, flow of fluid is stable even at start of evaporation due to action of centrifugal force, so that cooling effect in the moving blade is not disturbed.

Title: Testing method of substrate for electro-optical device
Inventor: ISHII MAKOTO
IPC: G01R31/02
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To make easily identifiable defects of pixels or the like even if the number of pixels is large, and pixel electrodes are fine as well as the pitches are narrow. SOLUTION: Pixel electrodes 118 formed on an element substrate 101 are connected to data lines via transistors. Further, sampling switches for sampling image signals supplied to image signal lines and supplying to data lines are formed on the element substrate 101. During testing, while applying an alternate current signal VAC to pixel electrodes 118 via an electro-conductive rubber 200, scanning signals are supplied successively to scanning lines as well as sampling control signals are supplied successively to the sampling switches. Here, if there is no defect, the alternate current signal VAC follows a route of 'pixel electrodes 118 → transistors →data lines → sampling switches →image signal lines'. Consequently, in an effective scanning period, if there is a period when the alternate current signal does not appear in the image signal lines, it is understood that there is a defect.
